When the page loads, I see an event under today's date that says "click here to read me". I then click on the calendar entry and... nothing happens. It took me a few seconds to figure out that I'm supposed to click on the description that appears in the left sidebar.

On a related note, the description in the left sidebar is the same as in the calendar view, except it also has a start time. You could just put the start time into the calendar view and get rid of the sidebar description altogether, saving users from a little extra navigation.
